BOUND GRAVEL INSPECTION AND MAINTENANCE GUIDE – DOWNLOAD
Bound gravel is a low maintenance product. However, it should undergo routine and operational inspection and maintenance to keep it in optimum condition.
Resin bound surfaces are intended to be used by normal pedestrian or vehicular traffic for which they have been designed. Protection should be provided wherever possible against abnormal damage. Heavy objects, such as waste skips, should not be dragged across the surface and protection should be provided during building and construction work to avoid unsightly contamination from oil, grease, cement and dirt. Spillage of solvents should be avoided as these will soften and damage the resin binder
Resin bound gravel is to be installed onto a minimum of 50mm AC14 open texture binder course.
A 1-3mm or 2-5mm aggregate is the most popular size used for a driveway, terrace or path, ensuring the internal build-up of the surfacing is a tight, well-bound mixture, with the right amount of cavitation for permeability. We recommend a minimum depth of 20mm for a driveway and a minimum depth of 16mm for a path or terrace.
For tree pits, we would recommend a 5-8mm or 10mm size aggregate to achieve optimum strength and porosity.
